Master is a title that has kind of fallen out of use in modern times, but it is sort of like the title Miss for girls. It used to denote a boy under 13 or sometimes an unmarried man, until the use of Mr became more common for men and boys over 13. It's still in use in England, though, I think, and other parts of Europe as well, but has fallen into disuse in America.

For instance, the Queen's grandson, Peter Phillips, was known as Master Peter Phillips when he was a baby, because he didn't have a title. Now that he's an adult, he's known as Mr Peter Phillips. See from the BRF's line of succession, how Peter, because he's an adult, is known as Mr, while his cousin, Samuel Chatto, because he's still a minor, is referred to as Master Samuel.

11. Mr. Peter Phillips
...
17. Master Samuel Chatto

I'm not sure how it is used in Norway, but I read on Wikipedia, and actually know by some experience, that young boys are referred here in the U.S. as Master in very formal situations (such as if they were a member of a wedding party). It's really only used in formal situations I think, and by the time they're thirteen or fourteen, it changes to Mister (Mr.), which is much, much more commonly used. I also noticed that they addressed Märtha-Louise's dauthers as Miss Maud Angelica Behn and Miss Leah Isadora Behn, so perhaps the website is just using the more formal title for the children. They also always address him with it in his biography, instead of saying just Marius. (ex. Master Marius attends primary school)

The Master title is only used in the English version, as is the Miss on Märtha Louise's daughers. Its Norwegian equivalents - Herr (Mr/Master) & Frøken (Miss) is not really in much use in Norwegian society any more. I think that one of the few times I've heard Frøken used (aside from about the only time I used it myself, in 1-2 grade for my teacher at times) is when Mette-Marit was marrying into the royal family, and the communications from the Palace about her. It is (sort-of) Palace-level formality to it, and even that, it seems, does not extend to children in Norwegian.

But she isn't a princess anymore, she has resigned her interference with the royal court of norway. Märtha louise is the black sheep of the family

Princess Ragnhild and Princess Astrid aren't Royal Highnesses either.
All 3, Princess Ragnhild, Princess Astrid and Princess Märtha lost their title as "Her Royal Highness" when they married commoners, but all 3 stayed "Princesses", as you can see in their profiles here: kongehuset.no - Kongefamilien
So, already 3 black sheep.

Apart from this: Mette-marit was not a Princess when Marius was born. and Marius' dad was not a prince. Prince Haakon didn't adopt Marius (as Morten Borg Hoiby still is Marius' dad and cares for him. As far as I know they have a good relationship).
So, why should Marius get a title?

He is completely included into the family. Even without any title. That's it.

But she isn't a princess anymore, she has resigned her interference with the royal court of norway. Märtha louise is the black sheep of the family

I didn't know that Martha-Louise is the black sheep of the family. Is that true?

I heard the King was displeased with some interview with Ragnhild but they made up but that's the last that I heard.

it.

But Märtha Louise lost her Royal Highness already on 01.02.2002 3 1/2 months before her marriage and the official reason given was because of her private business.

Yes, she is considered as a black sheep. Ari Behn, her husband is an failed author and an ex-addict. She claims that she can speak with ghosts, she is also the first Norwegian royalty who has been in court in front of a judge. Märtha Louise resigned her title, she didn't lost it. But she still uses the title princess to promote her books.

The Norwegian court is indeed a very strange one.. In sweden it would be considered unequal not to grant Marius a title, but is he adopted by CP. Haakon?

Why is the Norwegian court a strange one?
I don't see any problem. I really don't.
Every Royal House handels their family business in another way. Actually think, that the Norwegian court is probably the most liberal one. They included Marius right from the beginning. (Just like Ari Behn.)

Märtha lost her title because she decided to marry Ari Behn.

As I said before:
Marius is NOT adopted by Haakon, because Marius has a very good relation to his father Morten.

I didn't know that Martha-Louise is the black sheep of the family. Is that true?

Not necessarily. Who the black sheep of the family seems to change accordingly to what the press wants to focus on.

Märtha Louise gave up her HRH status some months prior to her marriage, because she wanted to focus on her own creative talents and use them in a business, as mentioned by Stefan. If she hadn't done so, it seems likely that the same procedure as with her aunts, Ragnhild and Astrid, would have been followed - the same procedure which was copied in Sweden with Princess Margaretha, Mrs Ambler, Princess Christina Mrs Magnuson and Princess Desirée, Baroness Silfverschiöld.

Her correct name is Princess Märtha Louise - it is not merely something she uses to promote books.

I have to admit I'm not too fond of Ari Behn's books - but I would not consider him a failed author.

Marius is not adopted by Haakon.

All this being said - can we get back on topic? Märtha Louise and Ari have perfectly fine threads of their own in their own subforum, even Astrid and Ragnhild have threads of their own….

Yes, she is considered as a black sheep. Ari Behn, her husband is an failed author and an ex-addict. She claims that she can speak with ghosts, she is also the first Norwegian royalty who has been in court in front of a judge. Märtha Louise resigned her title, she didn't lost it. But she still uses the title princess to promote her books.

As far as i know the norwegian King has no right to create Titles. So even if he would it is not possible for him to give marius an Title.

The Master title is only used in the English version, as is the Miss on Märtha Louise's daughers. Its Norwegian equivalents - Herr (Mr/Master) & Frøken (Miss) is not really in much use in Norwegian society any more. I think that one of the few times I've heard Frøken used (aside from about the only time I used it myself, in 1-2 grade for my teacher at times) is when Mette-Marit was marrying into the royal family, and the communications from the Palace about her. It is (sort-of) Palace-level formality to it, and even that, it seems, does not extend to children in Norwegian.

I also think they added it so that Marius has a "title" like the other children in the Crown Princes family. To me, it would be just like the CP family to want to try and make everything equal.

Is Marius still at Jansloekka School in Asker? Would he study at that school until he goes onto secondary school level? Do you think that he would go to Smestad eventually like Haakon?

Both Jansløkka & Smestad are only elementary schools. They only serve children from the age of 6 to the age of 12/13. Pupils from Jansløkka skole usually move on to Solvang Ungdomsskole (Solvang Middle School) - but it also happen in the Oslo-area go to Kristelig Gymnasium in Oslo for their Middle School needs as Haakon did when Märtha Louise started high school there. (More practical transportation and security-wise).

I suspect that Marius will continue on to Solvang, as the practical aspect of starting school in Oslo for middle school isn't there on the same level as it was for Haakon and Märtha Louise, who already went to school in Oslo and had friends there - Marius' circle of friends is most likely in his school and when many of those continue to Solvang, it would seem likely that he would do so as well.

As far as i know the norwegian King has no right to create Titles. So even if he would it is not possible for him to give marius an Title.

He can create titles, but only for those who are in line to the throne, which Marius isn't. Considering that he hasn't created titles for Maud Angelica and Leah Isadora, both of whom are in line to the throne, and is downsizing Sverre Magnus' status, it doesn't seem plausible that he'd even hand out a title to Marius if he could.

I don't think Marius will be able to recieve any type of title being he was not born a member of this family but became apart of this family through his mother's marriage to the prince.He is still accepted as a member of the family which is nice even though he carries no title at all.
